Task 1. Explain why or why not for each statement in 20 words. USE 4U CONCEPTS

1. A mixture of water and ice is at SATP. There is an equilibrium between water freezing and and ice melting.

2. The nuclear fission of 235U involves a highly negative H (-1.9 x 1011 J/mol). The Keq of this process is very large.

3. For the Haber process N2(g) + 3H2(g) 2NH3(g), if Keq = 1, when [N2] + 3[H2] = 2[NH3], the system is at EQ.
